桩基础的优化设计

Optimization design for pile foundation

针对工程优化设计中的离散变量,采用有限元分析软件建立有限元模型,根据整数梯度法原理编制离散变量的优化设计程序,对桩基础的桩间距进行优化,得到了桩间距的合理建议值,为桩基设计提供了合理的依据。

This article creates finite element model based on the FEM software, uses the integer gradient method to compile optimal design procedure to optimize pile spacing, obtains reasonable pile spacing suggestion value, provides available basis to pile foundation design.
